Carbohydrate biopolymers are one of the ecological alternatives to other organic corrosion inhibitors with toxic potential. In corrosion inhibition, they represent a set of chemically stable and environmentally friendly coatings for protecting metal surfaces, making them effective coatings for metal protection. Thus, this article presents a systematic review of carbohydrate biopolymers used as corrosion inhibitors since 2018. The investigation followed the PRISMA statement, which provides a meticulous summary of all available primary research in response to a research question. After including/excluding steps, forty-five studies were included in the review. The results are presented with a focus on the types of biopolymers evaluated, such as chitosan, cellulose, and gum arabic. In addition, the analyzed metals, the means used to accelerate the corrosion process, the type of inhibitor and the efficiency achieved in each study were also presented. In summary, this methodology helped to identify the main knowledge gaps in this area.
